Answer:

Yes. You did it correctly.

Step-by-step explanation:

The punnet square should be completed as follows:

T T

t Tt Tt

t Tt Tt

As the question says that the pollen carries the recessive alleles, hence the pollen should be carrying the alleles tt.

The question also says that all the offsprings produced are tall. Hence, the recessive male has to breed with a homozygous dominant female to get these results. The offsprings produced will be heterozygous dominant in this case.
